Book excerpt: The relaxation of poled nonlinear optical (NLO) chromophores in polymer films was characterized by infrared reflection-absorption spectroscopy. Both a guest-host system and a photocrosslinkable polymer system were investigated. Polymethylmethacrylate (PMMA) doped with either 2-methyl-4- nitroaniline (MNA) or 4(4'-nitrophenylazo) phenylamine (DO3) was studied. The photocrosslinkable polymer system, polyvinylcinnamate (PVCN) doped with 3- cinnamoyloxy-4-4-(N, N-diethylamino)-2-cinnamoyloxy phenyl azo nitrobenzene (CNNB-R) was also investigated. Doped NLO active molecules were aligned using the corona poling technique. Infrared spectra as a function of time were used to monitor the relaxation behavior of the oriented dyes after poling. Relaxation of NLO molecules was followed at various characteristic vibrational frequencies. The relaxation of MNA was found to be faster than that of DO3. The NLO dye molecule, CNNB-R was covalently bonded to the host polymer and formed a three dimensional crosslinked network after ultraviolet (UV) irradiation. Relaxation of NLO molecules in pristine and UV treated samples were compared. UV light induced crosslinking provided better temporal stability of molecular alignment in this system ...

Available in PDF, EPUB and Kindle. Book excerpt: The goal of gaining better understanding of the orientational decay mechanisms of poled nonlinear optical polymers and to develop a predictive description of the long time scale decay was well met. We developed a new experimental technique based on electric field induced second harmonic generation in the frequency domain to probe the polymer over many decades of time. This technique is best applied near the glass transition to probe frequencies from mHz to tens of kHz. We used this technique along with others to study a variety of polymers. Applying an Adams-Gibb model to the temperature dependence of the characteristic frequency, prediction of long term behavior at any temperature based on quick measurements near the glass transition temperature is possible. We also developed a new ultrafast laser source for studying nonlinear optical susceptibilities, and contributed to the study of cross-linked polyimide materials as stable and processable hosts for poled electro-optic polymers.
